Code for Sustainable Homes Assessment
Code for Sustainable Homes
The Code for Sustainable Homes is the standard by which new homes in Wales, England and Northern Ireland are now being judged for their green credentials. The CSH covers nine categories of sustainable design:
• Energy and CO2 emissions (M),
• Water (M),
• Materials (M),
• Surface Water Run-off (M),
• Waste (M),
• Health and Wellbeing (M),
Homes are assessed at the design stage and post construction. Each dwelling has its own assessment and, if it meets the required criteria, it is then awarded a certificate, ranging from Level 3 to Level 6, depending on performance.
The Code for Sustainable Homes (CSH) is an environmental assessment method for rating and certifying the performance of new homes. It is a Government owned national standard intended to encourage continuous improvement in sustainable home building.
The Code Assessors act as advisors on issues related to maintenance and development of the technical contents of the CSH standard and manage implementation of the scheme under contract to the Department of Communities and Local Government (DCLG).
Scope and Scoring
The minimum standards for Code compliance have been set above the requirements of Building Regulations. The Code is intended to signal the future direction of Building Regulations in relation to carbon emissions from energy use in the home, providing greater regulatory certainty for the homebuilding industry.
Achieving Code compliance at any level presents a significant challenge, particularly since there are mandatory (M) issues that need to be addressed. The highest levels need significant changes to conventional construction approaches, mainly due to the stringent requirements for reducing carbon dioxide emissions. Until recently, renewable-energy technologies and other low-emission technologies (e.g. combined heat and power [CHP] systems) were only found on homes owned by the keenest of environmentalists.
Although meeting the higher levels will never be easy, by planning ahead and taking a more strategic approach, developers can take every opportunity for improving the performance of their dwellings without resorting to ‘bolt-on technologies’. There are concerns that 'bolt-on technologies' may not be cost-effective and that customers may not perceive them as adding value. In fact, with a combination of good design and imagination, many of the credits and mandatory minimum performance standards can be met without any additional cost at all. If considered in a holistic way, developments can be created that are both environmentally and socially sustainable, and financially viable.
